Did you know there was a very secret payload on board the Dragon spacecraft, the first private spaceship to reach orbit and return safely to Earth? SpaceX didn't reveal what it was until today. The answer is deliciously funny.

It was a wheel of cheese! SpaceX CEO originally dropped a hint that if you liked Monty Python, you would enjoy the payload. The wheel of cheese is an ode to a skit from Monty Python's Flying Circus, where John Cleese tries to order cheese from a cheese shop that has no cheese. And we're sure there was some useful scientific testing that necessitates cheese too. [Universe Today via Geekosystem]
